About Us

Our Story

Thumb Cooling & Heating was founded in 1979 by Ron Mausolf with a simple mission: to provide honest, reliable heating and cooling services to families and businesses in Michigan's Thumb region.

What started as a small operation has grown into a full-service HVAC, plumbing, and electrical company, but our commitment to quality workmanship and customer satisfaction remains unchanged.

For over 45 years, we've been the trusted name for home comfort in Huron, Tuscola, and Sanilac counties. Our team of certified technicians brings decades of combined experience to every job, whether it's a simple repair or a complete system installation.
